NEW!! GREAT NEW MAYA CALENDAR SOFTWARE FOR THE I-PHONE: twiddle the cogs on your phon screen to find equivalent Maya dates :




Carol Cloudhart's Galactic Alchemy guides us through the 13-day pulses of the Tzolkin. This is the Q'iche (true count) 

  Free Mayan Horoscope software (download)

This is a great program by bob Makransky that includes photographs, a collection of Maya glyphs, explanations, and a Maya character analysis based on your birth -day in the Chol Qij (Tzolkin in Yucatec Maya language). Bob says;

"The bits and pieces of information and Chol Qij interpretations in this program are drawn from a variety of anthropological sources, and also from my experience of 25 years of living among the K'ekchi Mayans of Alta Verapaz, Guatemala (note that the term 'Mayan' - like the term 'Indo-European' - refers to a group of related but mutually unintelligible languages. At present there are some 25 Mayan languages spoken in Mexico, Guatemala, Belize, and Honduras. The Chol Qij - like the hieroglyphic alphabet - is pan-Mayan)."

There is also an facility to print out the "horoscope" and to see (and print) the stela of your birth date with the Long Count, Haab, Tzolkin and night-Lord glyphs (see zero day stela), but be warned, you will either be an absolute saint, or someone who is totally useless and liable to murder their relatives. For a more balanced analysis, see Bruce Scofield, below.

11 Most Versatile Online Calculators:  


1. MAYAN CALENDAR TOOLS  Online again, this is a massive calculator page, with 18 calculators; Mayan/Gregorian/Julian/Haab/Calendar Round/Tzolkin & more. Don't forget to set the JD correlation to 584283

2. AZTEC CALENDAR This converts Julian or Gregorian dates & gives the Aztec year, 13-day period, & Tonalpohualli (=Tzolkin) day, with colourful.Aztec glyphs. Pre-3114 - post-2012 NB Gives start-date as 6th September -3114 (see second group of Julian day calculators below) UPDATE: Advanced options: If you click on "Preferences", you can choose from 2 user modes; " Normal", and "Expert". In  Normal mode, you can choose from 2 correlations: Alfonso Caso (584283 or True Count); and Francisco Rodriguez Cortes (584280). In Expert  mode you can set any correlation, choose from "Terminal", or "Initial" year-bearer systems, and set "Year  constant" (the number  of the day in the year that occurred on the day with a zero long count). Changing the Year constant thus moves the Year-bearer; an  alternative to changing the Haab-day, since the Aztec equivalent to the Haab is not given).

The user can set the Long Count to modern calendar and Long Count to Calendar Round correlations to any desired value. The basic program function is to calculate the Base Date plus Distance Number and the Base Date minus Distance Number. It displays the results in both Long Count and Calendar Round. It also calculates and displays the modern calendar date (Julian, Gregorian or Julian Day Number), and all major sub-cycles such as the Direction / Color, the God of the Night, and the day within the Calendar Round, the Tzolkin, the Haab, and the 819-day cycle for each of the three dates."

2 Very Dodgy Calculators

New!! DOWNLOADABLE DREAMSPELL CALCULATOR: Gary Cooke's Dreamspell calculator can be downloaded to work offline. New Age count of Jose Arguelles) (UPDATED) (NOT 584283 correlated although Arguelles supports the end-date, 21/Dec/2012, his count shows 12 Manik on that day, not 4 Ahau, as calculated by the Maya)

This is good for those who want to compare Dreamspell to True Count: you could follow them both for a month to see which resonates best (you can also download one of the True Count calculators above for that side of the experiment). Let us know at Dire Gnosis if you do this experiment and what the results were. There is also a "Photon belt calculator" that is part of the Dreamspell calculator.

CALLEMAN CALCULATOR This is a new Long Count calculator for Carl Calleman's Long Count  correlation, that puts the end-point on October 28th 2011 (584283 correlated, but using Calleman's own Long Count Correlation, concocted to bolster his theory; implies that the Maya got it wrong!)

Countdown Clocks

I am getting fed up with all the disinformation about the end-date which is out there...that is why we have a guide to online date calculators and Julian Day Number calculators (see below) on this page. Most countdown clocks are wrong! See Whats new item 59. These can all be checked with the excellent FREE Geditcom  calculator - see below (just before Maya links). UPDATE: DEOXY.ORG is now correct! It was previously 6 MONTHS out!

SOULWISE CORRECT!!! MOST ACCURATE! terminates 21st December 2012 = end of Kali Yuga! "Years" = multiples of 365 days; "days" changes at midday & is most accurate at midnight

Julian Day Calculators (online)

According to the "True Count" correlation, in the Long Count = 11th August 3114 BC = Julian Day (JD) 584283. However, we must remember that this means 11th August 3114 BC as a Gregorian date, calculated backwards. Remember, the Julian Day number starts at noon, so could refer to the afternoon of one day,  or the morning of the following day. Hence, some calculators give fractions of the JD number. JD 584283 started at midday on August 11th 3114 BC. Remember also that 3114 BC = year -3113. All the following JD calculators agree that JD 584283 = 11th Aug -3113 (3114BC); the first 2 calculators (after the pink boxes) are accurate to minutes and seconds, so if they are set to  00:00:00 UT (midnight), on 11th Aug -3113, they will show  JD 584282.5. When set to 12.00.00 (midday) they show JD 584283.



                 Julian Day                                                  Julian Calendar (NB: calls 3114 BC "-3114")

Julian day:

Modified Julian day:

Adapted from Fourmilab's Calendar Converter



AAVSO    Updated  JD to Gregorian date. Also gives time (midday)

IWALUT    UPDATED JD to Gregorian date. Also gives Long Count, Haab & Tzolkin, (remember to put JD in "correlation number" box)

PAHAUTUN_a    JD to Gregorian date. Also gives day of the week.

PAHAUTUN_b    Gregorian date  to JD

There is a second group of Julian date calculators (see "Julian Calendar" pink box above) that convert the JD number to the Julian date NOT the Gregorian date. For example, if you enter August 11th 3114 BC (-3113) into these calculators, they will give  JD 584257. This has led to a lot of confusion. You must either enter the Julian date, or the JD number. For example, if you enter the JD 584283, they will give September 6th 3114 BC (-3113), which is the Julian date equivalent to the Gregorian date August 11th 3114 BC (-3113). This is why some sources have said the Long Count starts on September 6th 3114 BC, 26 days after the official start date, and so must end on JD 2456283, (584283 + 1,872,000 = 2456283) which is 8th December 2012 as a Julian date  - in other words, if Pope Gregory XIII had not instituted the calendar reform, on Feb 24th 1582, the Winter Solstice in 2012 (21st December in the Gregorian) would occur on Julian date 8th December  2012.



NR.COM         Julian dates (pre 1582) and Gregorian dates (post 1582) to JD and vice versa. So, according to this calculator, the Long Count started (584283) on 6th Sept 3114 BC (Julian) and ends on 21st Dec 2012 (Gregorian). Gives day of week.

BDL.FR   English site down til end of Jan 2005 - find French version here. JD to Julian date pre 1582 and vice versa; JD to Gregorian date and vice versa post 1582. As above

CSGNETWORK_a  Julian dates (pre 1582) and Gregorian dates (post 1582) to JD and vice versa. As above

NFRA.NL   JD to Julian date and Julian date to JD pre 1582. JD to Gregorian & vice versa after 1582. Accurate to hours, mins & secs (remember midday rule); As above, but also gives day of week

CSGNETWORK_b   JD to Gregorian and vice versa post 1582; JD to Julian and vice versa post 1582; JD to Julian ONLY, pre 1582. Gives day of week. (So you could get 8th Dec 2012 as an end-date here, but it would be the Julian date.)

ENRIQUE  Updated. Can be set to Gregorian or Julian - converts Long Count date at 584283 correlation. This is the only calculator which can be set to give both start dates (Julian & Gregorian) of August 11th -3113 and 6th September -3113; plus both end-dates: 8th December 2012 and 21st December 2012


and finally...

GEDITCOM  Downloadable, free calculator. Converts Julian dates to Gregorian dates & vice versa; counts number of days between 2 dates, (Gregorian and/or Julian) or months & days; or years, months & days. Also calculates the day of the week - very handy.

NEW!! Mayan Ruins detailed information about the history of Mayan ruins throughout Central America.


Maya Augury and Prophecy in the Books of Chilam Balam

A new page on Mike Finley's Real Maya Prophecies site (see below). Mike says,
I think it is the ONLY page on he Web that gives a reasonably full account of AUTHENTIC Maya divination, based on Maya sources. It is certainly the only page that includes a complete 260 day cycle of tzolk'in auguries from Maya sources (the Books of Chilam Balam written by Maya priest-shamans shortly after the Conquest), and a list of katun prophecies, including the prediction of the coming of Christianity, and the return of Kulkucan (Quetzlcoatl), which may in fact refer to the end of the long-count cycle in 2012 AD. (See also

Ekbalam  Maya calendar pages with very clear images of day, month & Lord of Night signs.  

The Real Maya Prophecies: Astronomy in the Inscriptions and Codices: This site is an exciting find! The  author, Mike Finley, comes from a fairly orthodox angle, but also has a lot of respect for Jenkins' work. He has provided some myth-busting pages on people with faulted Maya-based theories. There is also information on the Codices and more...PLUS the most impressive all-round free, downloadable calculator - see calculator section, above.

 The Katun Prophecies Bruce Scofield's astrological analysis of the Short Count gives predictions for this katun & the next katun, starting in 2012.

20 Mayan Calendars: Aluna Joy claims there are 20 Mayan calendars, one of which is called "OX LAJUJ BAKTUN", (NB not to be confused with OX LAHU BAKTUN - the 13 baktun cycle) and lasts 100 calendar rounds (100 x 52 years = 5200 years), terminating in 2012...if true, this could vindicate Gordon Brotherston's work on the Aztec Sunstone. (Gordon Brotherston found evidence of the 26,000-year cycle of precession encoded on the Aztec Sunstone, in the form of 5 eras, of 5200 years each (see Brotherston's Book of the Fourth World p.115-116) However, Brotherston calculated forward from a "3113 BC" start point to a 2088 end-point Aluna Joy says it terminates in 2012, which infers that the cycle must have started in 3189 BC if calculated as 5200 tropical years, or 3185 BC if calculated as civil (365-day) years, of which there are 52 per Calendar Round. Alternative link updated .

Maya Calendar and Cosmology  The essential site for understanding the whole 2012 question. John Major Jenkins, author of Maya Cosmogenesis 2012, explains what the Long Count was measuring, the correlation controversy; interviews Adrian Gilbert about The Mayan prophecies, plus loads more. 

Mesoamerican Calendars (Resonate) Another great site, with an introduction by Jenkins, loads on the correlation issue, with a reply from Arguelles over his  Dreamspell count, which misses a day every leap year, unlike the Tzolkin count still used in Guatemala, which is unbroken.

Mesoamerican Calendars (meX-Files) Also titled Pre-Columbian Calendars, though not visibly, this site also has an Aztec Sunstone page and a calculator (True Count) for Maya, Mexica & Zapotec calendars.

The Maya Calendar (Maya World Studies Center)    This is a good site, but remember the date calculator is not on the "True Count", but the earlier 584285 correlation (terminates 2 days later on 23/12/2012) see Jenkins for discussion.
